5. Your clinginess

Thinkstock

Perhaps you and your girlfriend usually make like Velcro and fur when you’re out on the town, but when meeting her friends, don’t assume that you should be overly loving toward her. Yes, they want to be reassured that you care for her (a bit of affection always goes down well), but you don’t want to be clingy with her physically — or emotionally, for that matter. Don’t be keeping an eye on her when she notices the group of handsome men that enter the restaurant or club, don’t stick to her during a night out or make like you have to be around her every five seconds. This will make her friends think you’re a jealous/possessive type. In other words: not good news for their friend.
